Air Force Scientific Advisory Board Study on Technology Options for Improved Air Vehicle Fuel Efficiency

As shown in Figure 1-3, the AFSAB stated that the United States currently depends on foreign sources for 63 percent of its annual fuel utilization (AFSAB, 2006; Karagozian, 2006).

That dependency is projected to grow to 70 percent by 2025. The government used 1.7 percent of the total annual fuel consumption of the United States in FY03. As already stated in the discussions accompanying Figures 1-1 and 1-2, DoD was the largest fuel consumer, with 97 percent of government fuel usage attributed to DoD. Within DoD, the Air Force used 53 percent of the total fuel. Finally, as
